Vikings came from all of the Nordic Countries, if you want to generalise, the Swedes went East, the Norwegians West and South (they even served for the Byzantine King as his bodyguards), and the Danish went mainly to Western Europe and England where they at times ruled (Danelagen). (I said it was a generalization!!)
William the Conqueror had Vikingblood in his vains as he was a descendant of Gange-Rolf (who is either Norwegian or Danish, this is debated, but I ofc chose to believe he was Norwegian ).
More viking based trivia;
-at the end of the Napoleonic Wars, Sweden was given Norway as a prize. At this time Norwegian territories also included Iceland and Greenland. All of Norway was ruled again by Denmark in a Union (Denmark-Norway). The Swedish diplomat arriving to sign the peace treaty however forgot to include Iceland and Greenland in the treaty, and they became Danish as a result.
-contrary to popular belief, the most valuable naval asset for the Vikings was not the longboat, but rather the Knarr, which was a trading vessel.
-contrary to popular belief, the vikings valued trade and peace, and were not the crazed mushroom-high warriors depicted in Hollywood.
-Viking men were almost obsessed with their appearance, and in old temporary English texts, there are several complaints about how the viking men looked so good that they got the English women to leave their husbands to go live with the Vikings.
-The Viking-Era is said to start with the raid of the Lindisfarne-Monestary in 793 AD, and is often said to end with the failed attempt to seize power in England in 1066.
Terje (which is a rewrite of the older Tarjei, which is a rewrite of the even older Torgeir, which when split becomes Tor and Geir. Tor ofc is the Norse God amongst other assosiated with thunder, and Geir comes from the norse word Atgeir, meaning Spear)
